Bathymetric range and biodiversity within the monophyletic, deep-sea Chrysogorgiidae (MCC).

Diversity: morphology estimate based on number of nominal species; genetic estimate based on number of mtMutS haplotypes. N: sample size (morphology: number of biogeographic records, and minimum number of colonies in parentheses), Atl: Atlantic Ocean, Ind: Indian Ocean, Pac: Pacific Ocean, Ant: Antarctic Ocean. Some depth estimates are based on depth ranges from trawling stations, in which case minimum and maximum depths were averaged (see notes in the Material and Methods section).
